Please create a method that will convert the old expressions to new format and make them re-usable again.

One workaround is to remove nodes that are not visible, e.g., in the Page_Load event:

RadNavigation1.Nodes.RemoveAll(x => !x.Visible);

Another workaround is to remove the HTML of hidden nodes. Note that this will not affect the nodes collections and they will still be present. Invoking operations or methods on such removed nodes can cause errors.

			<telerik:RadNavigation runat="server" ID="RadNavigation1" OnClientLoad="OnClientLoad">
				<Nodes>
					<telerik:NavigationNode Text="first"></telerik:NavigationNode>
					<telerik:NavigationNode Text="second" Visible="false"></telerik:NavigationNode>
					<telerik:NavigationNode Text="third"></telerik:NavigationNode>
				</Nodes>
			</telerik:RadNavigation>
			<script>
				function OnClientLoad(sender, args) {
					var nodes = sender.get_allNodes();
					var indicesToRemove = [];
					for (var i = 0; i < nodes.length; i++) {
						if (nodes[i].get_element().style.display == "none") {
							$telerik.$(nodes[i].get_element()).remove();
						}
					}
				}
			</script>

Using the set_enabled() method of the NumericTextBox doesn't disable/enable the TextBox properly:

<telerik:RadCheckBox runat="server" ID="CheckBox1" OnClientCheckedChanged="onClientCheckedChanged" Text="Enable/Disable" AutoPostBack="false" />
<telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" />  

function onClientCheckedChanged(sender, args) {
    let numericTextBox = $find("<%= RadNumericTextBox1.ClientID %>");
    let isChecked = args.get_checked();

    numericTextBox.set_enabled(isChecked);
}

We have the latest update for Ajax installed today and have found an issue with the RadSpell control. If you type a value of 'tha' into a textbox/text area control that spell check will target, you will get an error 'Uncaught SyntaxError: Unterminated string in JSON' error in the console. This is able to replicated within the demo page of the Spell control.

https://demos.telerik.com/aspnet-ajax/spell/examples/overview/defaultcs.aspx?_gl=1*19wdrka*_gcl_au*NTA5NTg2MDEuMTc0MDYwNDU5NQ..*_ga*MjA4NzU2NTg4MC4xNzQwNjA0NTkx*_ga_9JSNBCSF54*MTc0MDYwNDU5MS4xLjEuMTc0MDYwNjI5Mi42MC4wLjA.

Remove the text in the first textbox in this page and replace it with 'tha' and in the console you will see the error shoot off.

I am experiencing an issue in the Telerik Rad Editor where, after copying and pasting a long sentence in a single line, if I apply bold formatting to a word and place the cursor at the beginning of the bolded word, pressing Enter results in an empty line being inserted between the text. This behavior is reproducible on the Telerik webforms editor demo site as well.

I would appreciate any guidance on how to resolve this issue. Thanks in advance.

Hello All,

I'm using a couple of Radbuttons to enable users to download some forms (in Word). This has stopped working in Chromium based browsers for some reason (new Edge, Chrome). It still works in Internet Explorer. No errors in the browser DevTools and no error on the server either.
It also does not work in Cassini (VS2017).

Not sure where to go from here - can anyone confirm/deny?

TIA - Marcus.

<telerik:RadButton ButtonType="LinkButton" RenderMode="Lightweight" ID="btnName" runat="server" Text="Button Text" CssClass="TemplBtn" NavigateUrl="~/assets/someform.docx">

</telerik:RadButton>

When creating and upgrading Telerik UI for AJAX projects to version 2025.1.211 using "InstallFolder" distribution Telerik UI for ASP.NET AJAX references are not added to the project.

Error thrown:
Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: 'maxDate' is not a property or an existing field.

Setup for reproduction:

<asp:ScriptManager runat="server" ID="ScriptManager1"></asp:ScriptManager>

<telerik:RadDateRangePicker runat="server" ID="RadDateRangePicker1" 
MinDate="2022-05-01" MaxDate="2022-05-01">
</telerik:RadDateRangePicker>

When pasting bullet lists from Microsoft Word into the editor, extra leading spaces (&nbsp;) appear in the list items. This causes unexpected indentation and formatting issues.

Before 2025 Q1

In 2025 Q1

After upgrading to 2025 Q1, RadGrid throws the exception: 

Uncaught TypeError: t is not a function

The default font size on the client is not saved explicitly on the Excel file, so the Excel defaults take over (11px Calibri), so upon subsequent import all cells will have that font.

Steps to repro:

    go to https://demos.telerik.com/aspnet-ajax/spreadsheet/examples/import-export/defaultcs.aspx 
    export the file
    import the file

Expected: nothing changes

Actual: all cells are 11px Calibri
Workaround: Set a default font when the cell font is null
 
public override void SaveWorkbook(Workbook workbook)
{
    string path = "C:\\path-to-output.xlsx";
     
    for (int i = 0; i < workbook.Sheets.Count; i++)
    {
        for (int j = 0; j < workbook.Sheets[i].Rows.Count; j++)
        {
            for (int l = 0; l < workbook.Sheets[i].Rows[i].Cells.Count; l++)
            {
                string fontFamily = workbook.Sheets[i].Rows[i].Cells[l].FontFamily;
                workbook.Sheets[i].Rows[i].Cells[l].FontFamily = !string.IsNullOrEmpty(fontFamily) ? fontFamily : "Courier New";
 
                double? fontSize = workbook.Sheets[i].Rows[i].Cells[l].FontSize;
                workbook.Sheets[i].Rows[i].Cells[l].FontSize = fontSize.HasValue ? fontSize : 12;
            }
        }
    }
    workbook.Save(path);
}
 

I like to add my own buttons in the toolbar, for example to open new Windows, add more text to the description, specify if I like or dislike the picture.

Moving of folder from the tree to the grid works, but event is not raised. Also, there is no other suitable event that handles the situation. 

The following patch will raise the event, but  you should make sure to remove the override once the bug is fixed: 

<telerik:RadFileExplorer RenderMode="Lightweight" runat="server" ID="FileExplorer1" EnableCopy="true"
    OnClientMove="OnClientMove" OnItemCommand="FileExplorer1_ItemCommand" >
    <Configuration ViewPaths="~/Images" UploadPaths="~/Images"
        DeletePaths="~/Images"></Configuration>
</telerik:RadFileExplorer>     
 
<script>
    var origFunction = Telerik.Web.UI.RadFileExplorer.prototype._onTreeNodeDropping;
 
    Telerik.Web.UI.RadFileExplorer.prototype._onTreeNodeDropping = function (sender, args) {
        origFunction.call(this, sender, args);
        var destNode = args.get_destNode();
        if (!destNode) {
            var destElement = args.get_htmlElement();
            if (!destElement) return;
            var gridElement = this.get_grid();
            var grid = gridElement != null ? this._isOverElement(destElement, gridElement.get_id()) : null;
            if (grid) {
                var isCopying = this._enableCopy && args.get_domEvent().ctrlKey;
                var eventName = isCopying ? "copy" : "move";
                var args2 = new Telerik.Web.UI.FileExplorerEventArgs(this.get_tree().get_selectedNode(), this.get_currentDirectory());
                this.raiseEvent(eventName, args2);
            }
        }
    }
 
    function OnClientMove(sender, ev) {
        // Do something
    }
</script>

Steps to reproduce:
1. go to demo url http://demos.telerik.com/aspnet-ajax/editor/examples/edittemplate/defaultcs.aspx
2. click add new record
3. try to manually resize editor. it won't.
4. click add new record again.
5  try to manually resize editor, now it will.

A workaround is to access the column and replace the text of the cell with a <label> control. Examples are attached below
